Hey, trying to install some piston rings w/out any instructions and wondered if anyone here might know a source for proper piston ring order and orientation.
One ring marked DY has a bevel on inside (opposite from 'dy' mark) and endgap of .25-.30mm.
Other ring is marked D is squared off and endgap of .30-.40mm.
Two Problems:
1. Which goes on top? (Beveled or squared?/ DY or D?)
2. Endgap is within spec for Honda, but not CF Moto ( Honda is .15-.35mm and CF Moto is 15-30mm/.10-.25mm. Does it make a difference? Piston and cylinder are exact same size. Why would there be separate specs for same engine? Differences in ring material??
Thoughts?
Thank you.
